Vent Pipe Covering System

Abstract

A vent pipe covering system for efficiently forming a seal between a vent pipe structure and a supporting structure. The vent pipe covering system generally includes a base, a body extending from the base and a coupler extending from the body opposite the base. The base includes a first opening and the body includes a passageway, wherein the passageway longitudinally extends through the body and interconnects with the first opening. The coupler includes a retaining cavity to extend over an outermost end of a pipe extending through the passageway and the first opening, wherein the body and passageway may expand and retract to accommodate various length pipes via an expandable portion of the body.

AI Technical Summary

Benefits of technology

[0015]The general purpose of the present invention is to provide a vent pipe covering system that has many of the advantages of the vent pipe covers mentioned heretofore. The invention generally relates to a cover for a vent pipe which includes a base, a body extending from the base and a coupler extending from the body opposite the base. The base includes a first opening and the body includes a passageway, wherein the passageway longitudinally extends though the body and interconnects with the first opening. The coupler includes a retaining cavity to extend over an outermost end of a pipe extending through the passageway and the first opening, wherein the body and passageway may expand and retract to accommodate various length pipes via an expandable portion of the body.

[0018]An object is to provide a vent pipe covering system for efficiently forming a seal between a vent pipe structure and a supporting structure.

[0023]Another object is to provide a vent pipe covering system that is easy to install.

Problems solved by technology

Many of these covering structures falter for various reasons, such as but not limited to not conforming to varying size vent pipe structures 20, difficulty installing and various others.

In addition, some prior covering structures attempt to provide a pressurized seal between the extension pipe 22 or the main pipe 21 and the covering structure; however this pressurized seal may be difficult to maintain in cold weather climates.

Another problem with prior covering structures is some may provide a rigid sealing structure (i.e. not allow main pipe 21 to move up or down) between the main pipe 21 and the support structure 12.

This can result in the seal being broken or damaged with the support structure 12 because of the rigid manner in which the extension pipe 22 was originally sealed.
